According to Gawker Media's ValleyWag blog, they are reporting a security breach on AT&T's website which has allowed public access to iPad 3G customer's email addresses and SIM card identifier numbers of over 114,000 iPad 3G users on the network.

It doesn't stop there. According to the data we were given by the web security group that exploited vulnerabilities on the AT&T network, we believe 114,000 user accounts have been compromised, although it's possible that confidential information about every iPad 3G owner in the U.S. has been exposed. We contacted Apple for comment but have yet to hear back. We also reached out to AT&T for comment. A call to Rahm Emanuel's office at the White House has not been returned...... that includes thousands of A-listers in finance, politics and media, from New York Times Co. CEO Janet Robinson to Diane Sawyer of ABC News to film mogul Harvey Weinstein to Mayor Michael Bloomberg. It even appears that White House Chief of Staff Rahm Emanuel's information was compromised.....

The security hole has since been patched by AT&T, however the damage cannot be undone, and AT&T made no effort to notify it's customers of this breach. I for one would like to know if my information has been compromised, especially when I pay monthly for their service and trust their accountability.

While the blame isn't exactly clear, Gawker seems to think that both sides are to be held accountable for this unfortunate error. They actually have quite an in-depth article explaining how this happened and what exactly the process was. I highly suggest taking a read if you want to further understand how these leaks can happen.

The subscriber data was obtained by a group calling itself Goatse Security. Though the group is steeped in off-the-wall, 4chan-style internet culture—its name is a reference to a famous gross-out Web picture—it has previously highlighted real security vulnerabilities in the Firefox and Safari Web browsers, and attracted media attention for finding what it said were flaws in Amazon's community ratings system.

Wow, everyone get off of AT&T's back on this one, they were hacked, they didn't expose the information. Change the title, this is an attack on AT&T's credibility that is not needed. Anyone can get hacked.

It doesn't matter how much money the company has and such..when it comes to exploiting/hacking a site,money can't buy security.NASA was hacked into a decade or so ago,so was CIA,Tons of banks,etc.It just gets fixed and the world goes on.
